388.15 is what percent of 621.05 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 621.05 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 621.05, so we can write it down as 100%=621.05.
4. We know, that x% equals 388.15 of the output value, so we can write it down as x%=388.15.
5. Now we have two simple equations:
1) 100%=621.05
2) x%=388.15
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=621.05/388.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 388.15 is what percent of 621.05

100%/x%=621.05/388.15
(100/x)*x=(621.05/388.15)*x       - we multiply both sides of the equation by x
100=1.6000257632359*x       - we divide both sides of the equation by (1.6000257632359) to get x
100/1.6000257632359=x
62.498993639804=x
x=62.498993639804

now we have:
388.15 is 62.498993639804% of 621.05
